Issues within a lister

Turn on Preferences / Folders / Folder Sizes / Update folder sizes after file operations where possible.

Confirmed. Currently the queue icons only work in the main folder, not expanded sub-folders. We do hope to improve this in the future.

Unfortunately Everything doesn't index "size on disk" information so when Everything is being used for folder sizes the size on disk shown is just an estimate based on the block size, and doesn't take compression into account.

That's a good suggestion, we already have plans to improve filtering when Flat View is active so will take this idea into account as well.

Also generally, please ask one question per thread.
